IMPROVEMENT IN MACHINES FOR SAWING FELLIES.

` Specification forming part of Letters Patent No. 126,768, dated May 14, 1872.

Specification describing anew and Improved Felly-Sawing Machine, invented by JOHN B. ZIMMERMAN of Fort Seneca, in the county of Seneca and tate of Ohio.

The invention consists in improving machines for sawing both curved sides of a felly, as hereinafter fully described and subsequent- 1y pointed out in the claim.

The saws are mounted in the sash, so that they may be turned around on their vertical axes to shift for sawing straight stuff, when the felly-carriage is removed and a straight guide applied. Onel of the saws is adjustable',

toward and from the other, for cutting different thicknesses. A

Figure l is a sectional elevationv of my iinproved sawing-machine, and Fig. 2 is a horizontal section.

Similar letters of reference indicate corresponding parts.

A represents the frame 5 B, the gate 5 C, the connecting-rod; D,the crank ordriving-wheel; and E, the table, all of which are substantial- 1y like the ordinary sawing-machines of this character. I arrange two saws, F, in the said gate, as far apart as the depth of the felly to be sawed, for sawing both the outer and inner curves at once; and the saws are arranged for adjustment toward or from each other by having the straining-bolts a, fitted in slotted plates b, to vary them for fellies of different thicknesses 5 and I combine with said saws a circular carriage, J, pivoted in front of the sawat G, the said pivot being as far from the saws as the radius of the wheel for which the fellies are designed, and the said carriage is to be provided with numerous center-holes, H, for the pivot-pin, to shift it for cutting fellies for wheels of different sizes. I represents spring clamps, with clamping eccentrics K arranged on the carriage so as to clamp the" plank to be sawed at each end by being forced down on the top of it, as shown, to hold it while sawing. 4

By taking out one saw yand turning the other a quarter of a revolution it may be used for ordinary straight or curved sawing 5 and by turning both saws about an 'eighth of a revolution and ixing a gauge parallel with them the two may be used for sawing straight parallel stuft', and the adjustable onemay be shifted for stuff of different widths.

Having thus described my invention, I claim as new and desirey to secure by Letters Patenti The vibratory feed-carriage, provided with spring clamps l I, slatted near their ends, and tting over posts, to which are pivoted camlevers K K, as and for the purpose described.
